HAL Tejas

This is a timeline of the development of the HAL Tejas, a light-weight, multirole fighter aircraft manufactured by Hindustan Aeronautics Limited.



  • Indian government accepted the recommendation by its Aeronautics Committee that Hindustan Aeronautics Limited (HAL) should design and develop an advanced technology fighter aircraft around a proven engine



  • HAL completed design studies in 1975, but the project fell through due to inability to procure the selected "proven engine" from a foreign manufacturer and unfulfilled IAF requirements.



  • DRDO obtained permission to initiate a programme to design and develop a Light Combat Aircraft



  • IAF submits Air Staff Requirements (ASR) for LCA in October 1985. This was initiated by the then Air Chief Marshal Idris Hassan Latif.


  • Government allocates 575 crores for the LCA programme.
  • Programme to develop an indigenous powerplant (engine) was launched at GTRE.


  • Project definition commenced in October 1987 with French Dassault Aviation as consultants.


  • Project definition completed in September 1988.


  • Government review committee expresses confidence in LCA programme. It was decided that the programme will be carried out in two phases.



  • Design of LCA was finalised as a small delta winged relaxed static stability aircraft.
  • Phase 1 of the development was commenced to create the proof of concept system. Financial problems within India prevented full scale operations from starting.


  • Full funding started from April 1993 full-scale development work for phase 1 started in June.


  • First technology demonstrator, TD-1, rolled out on 17 November 1995 and was followed by TD-2 in 1998. However, technical problems in flight control systems and structural deficiencies plagued the prototypes and they remained grounded.


  • Multi-Mode Radar (MMR) for LCA design work started at HAL’s Hyderabad division and the LRDE.



  • 4 May - LCA’s maiden flight successfully completed by Technology Demonstrator TD-1, on 2001. Prime minister Atal Bihari Vajpayee renames LCA as Tejas.
  • Development assistance sought from Snecma on the Kaveri engine.[1]


  • 6 June - TD-2 makes a successful maiden flight.
  • MMR system was reported to be not working as per the criteria laid down in requirements.


  • 25 November - PV-1 makes a successful maiden flight.


  • 1 December - PV-2 makes a successful maiden flight.


  • 13 May - The PV-2 went supersonic for the first time
  • 14 May - The PV-2 went supersonic again, but this time in a weaponised state (i.e., carrying weapons such as missiles and an internal gun).
  • 1 December - The PV-3 flew for the first time for 27 minutes at an altitude of 2.5 km and at a speed of Mach 0.8. The PV-3 was equipped with a more advanced pilot interface, refined avionics and higher control law capabilities compared with the previous versions.

  • 25 April - The first Limited Series Production LCA (LSP-1) made its first flight and it reached a speed of Mach 1.1.
  • PV-2 and PV-3 underwent sea-level trials at INS Rajali Naval Air Station, Arakkonam to study the effects of flying at sea-level, as all earlier trials have been conducted at Bangalore which is 3,000 feet (910 m) above sea-level.[2][3] The reliability of the LCA systems under the hot and humid conditions, as well as low level flight characteristics was tested.[4][5] It is due to this intense flight testing schedule that the LCA was not able to fly at the Paris air show-2007, as was originally planned.[6]
  • 7 September - Tejas Prototype Vehicle (PV-1) made a successful maiden flight with two 800 litre drop tanks.[7][8]
  • 25 October - Tejas PV-1 fired a Vympel R-73 missile for first time. The trials were conducted off the Goa coast at INS Hansa Naval Air Station.[9]
  • 11 December - LITENING targeting pod was successfully tested on Tejas PV-2.[10]


HAL Tejas high-altitude trials at Leh successfully completed by December 2008.
  • 7 February - Tejas Prototype Vehicle (PV-1) made a successful flight powered by fuel from two 800 litre drop tanks. It made a one hour and 24 minute long sortie. On internal fuel LCA can perform a 40-minute sortie.[11]
  • April - First Flight with HMDS[12]
  • LCA Tejas prototypes PV-2 & PV-3 underwent hot weather flight trials at Air Force Station, Nagpur from 28 May 2008 to 4 June 2008. The trials were declared successful.
  • 16 June - Tejas second Limited Series Production LCA (LSP-2) made its first flight and it reached a speed of Mach 1.1.
  • 7 November - LCA Prototype Vehicle-3 made first successful night flight.[13]
  • 13 December - PV-3 and LSP-2 completed the high altitude trials at the Leh air base.[14]


  • 22 January - Tejas completed 1000 flights.[15]
  • February - the live bombs test were successfully carried out.[16]
  • October - PV-3 and LSP-2 completed visual target elimination and air-to-ground weapons delivery trials.[17]
  • 26 November - Two seater (Trainer) version of Tejas(PV-5) made its maiden flight on 26 Nov 09.[18]
  • 7 December - Tejas passed flight flutter test diving from an altitude of four kilometers to almost sea level at 900 feet (270 m). Tejas recorded a speed over 1350 km/h. These tests were conducted at INS Hansa, Goa.[19]
  • 15 December - Indian government sanctioned Rs 8,000 crores to begin production of the fighter jet for the Indian Air Force and Indian Navy.[20]



  • 23 April - LCA Tejas LSP-3 Makes Maiden Flight. LSP-3 is almost the final configuration including the new air-data computers, Hybrid Multi Mode Radar, new communication and navigation equipment and radar warning receiver. With this the LCA programme has completed 1350 test flights logging about 800 flying hours.[21]
  • 2 June - LCA Tejas LSP-4 Makes Maiden Flight. The flight marks the first time for a Tejas aircraft flying in the configuration that will be finally delivered to the Indian Air Force.[22] In addition to the Hybrid MMR, the aircraft also flew with a functioning Countermeasure Dispensing System [23]

  • 10 January - Certification for the Release to Services with assured safety and specified performance for IOC.[25]
  • 26 January - LCA Tejas participates in the 26 January Republic Day Celebrations by being paraded at New Delhi.
  • September - LCA Tejas undergoes bombing runs at Pokhran Test Range.


  • 9 March - LCA Tejas LSP-7 Makes Maiden Flight[26]
  • 27 April - 1st Naval LCA prototype NP-1 makes maiden flight.[27]
  • 27 June - HAL Tejas (LSP 2, 3 and 5) completed precision bombing runs in the desert of Rajasthan, for the second time.[28]


  • 31 March 2013 - LSP 8 had a successful maiden test flight at Bangalore.[29]
  • 28 Sep 2013 - The Light Combat Aircraft (LCA) Tejas successfully completed the maiden engine relight test on Friday—a critical parameter the programme needs to achieve for the Initial Operational Clearance 2 (IOC-2). The Limited Series Production (LSP-7) aircraft from the Tejas flight-line, piloted by Gp Capt R R Tyagi, underwent the engine relight test at 1 pm. The LSP-7 was chased by a Hawk aircraft.[30]
  • 20 December 2013 - LCA successfully achieves IOC-2.


  • 28 May 2014 - LSPs 3, 5 and 7 successfully complete advanced weapons trials.[31]
